The application of ICP accelerometer sensor signal in a data recorder

This introduces a conditioning circuit design base the data recorder about ICP accelerometer sensor signal. For the characteristics of ICP type of sensor, show the composition of the conditioning circuit, Anti-aliasing low-pass filtering principle and specific design ideas of hardware, implement the conditioning of ICP accelerometer sensor signal which can be collected. Study the means of the frequency response of the circuit by the experiments, show the frequency response data list and the amplitude-frequency characteristic curve finally, and using linear regression approach to estimate the attenuation slope of the circuit.
